Each time I add a line to the custom CSS and click “Save and Publish” the entire configuration disappears e.g.

My slider completely disappears from the system.

My chosen skin selection reverts back to the default blue.

My uploaded logo selection is gone (but the logo still remains in Media).

etc. etc.

The Site Title and Tagline remain intact, however.

On my slider images in the Media library,

Add to a slider (create one if needed)

is still set to Yes. However, because there is no slider in the system in the Choose Slider section a message says, “You haven’t create any slider yet. Write a slider name and click on the button to add you first slider.”

So some, but not all of the Customizr settings vanish. Please tell me what I have to do to make this stop happening.

I think I know what causes the problem. When I first enter the following CSS it works fine. I had to use HTML entity reference because it’s the only way I could get the fallen leaf icon to display. Note: for this post I had to put a space between & # so that the fallen leaf icon would not be displayed:

.page h1.format-icon:before {
content: "& #127810;"
}

But later, when I refresh the Custom Customizr web screen I notice that the entity reference has changed to the UTF-8 Unicode Character ‘FALLEN LEAF’:

.page h1.format-icon:before {
content: "🍂"
}

The HTML entity encoding, & #127810;, is replaced by the UTF-8 Unicode Character, 🍂, and when I click Save & Publish an error occurs and my Customizr configuration is lost. Customizr does not like UTF-8.

The reason I used the HTML entity was because the ASCII did not work:

.page h1.format-icon:before {
content: '\1F342';
}

and neither did the following, which displayed “1F342” on the web page in place of the icon:

.page h1.format-icon:before {
content: “\1F342”
}

So the HTML entity works properly until I attempt to edit Custom Customizr CSS settings. Also, none works as it should:

.page h1.format-icon:before {
content: none;
}

So I know the selector is correct. Why is the ASCII not working for me? I would use it in lieu of HTML entity if it would work.
